Abstract

PURPOSE:To largely improve mounting efficiency of first and second substrates in case of mounting the second substrate on the first substrate by providing the first substrate having an elastic connecting part to be twisted to be deformed, and the second substrate having an engaging hole. CONSTITUTION:Hooklike connecting parts 10 formed at four corners of a chassis have elastic properties and are previously twisted to be deformed. Thus, when the parts 10 of the chassis 2 are inserted into the engaging holes 5 of a control substrate 3, the parts 10 are deformed to be inserted, the contacts 10a of the parts 10 are brought into contact with the rear face of the substrate 3, and the substrate 3 is mounted on the chassis 22. Thus, mounting efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a board mounting device used, for example, when mounting a control board to the chassis of a digital audio tape player (DAT).

[Prior Art] FIG. 4 is an overall perspective view of a DAT, and FIG. 5 is an exploded perspective view of the main parts of FIG. 1st
3 is a control board as a second board that drives and controls a capstan motor (not shown) etc. on the chassis 2; 4 is a locking portion provided at the four corners of the chassis 2; These are locking holes formed at the four corners of the control board 3 to correspond to the locking portions 4.

In the above DAT, when attaching the control board 3 to the chassis 2, the locking part 4 is inserted into the locking hole 5, and then the locking part 4 is twisted and deformed to be locked in the locking hole 5. (See Figures 6 and 7).

[Problems to be Solved by the Invention] In the conventional board mounting device configured as described above, after the locking portions 4 are inserted into the locking holes 5, the locking portions 4 must be manually twisted and deformed one by one. First, there was a problem that the installation efficiency was poor. This invention was made to solve the above-mentioned problems, and an object of the invention is to provide a board mounting device that improves mounting efficiency.

[Means for Solving the Problems] A board mounting device according to the present invention includes a first board having a torsionally deformed elastic locking part, and a first board having a locking hole that is locked to the locking part. It is equipped with two substrates.

[Operation] In the present invention, the locking portion is torsionally elastically deformed and inserted into the locking hole and locked, and the second board is attached to the first board.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are perspective views of essential parts showing one embodiment of the present invention, and FIG. 3 is a sectional view of essential parts of FIG. 2, and the same or equivalent parts as in FIGS. A reference numeral is given and the explanation thereof will be omitted.

In the figure, reference numeral 10 denotes hook-shaped locking portions provided at the four corners of the chassis 2, and the locking portions 10 have elasticity and are twisted in advance.

In such a board mounting device, when the locking portion 10 of the chassis 2 is inserted into the locking hole 5 of the control board 3, the locking portion 10
is deformed and inserted, the abutting portion 10a of the locking portion 10 contacts and locks the back surface of the control board 3, and the control board 3 is attached to the chassis 2.

Although the above embodiment describes a board mounting device applied to a DAT, the present invention is of course not limited to this DAT, and can be applied to a device for mounting boards together. Alternatively, a locking hole may be formed in the chassis and a locking portion may be provided in the control board.

[Effects of the Invention] As explained above, the board mounting device of the present invention has the following effects:
Since the first substrate has a torsionally deformed elastic locking portion and the second substrate has a locking hole that is locked to the locking portion, the locking portion can be inserted into the locking hole. By simply doing this, the second board can be easily attached to the first board, and the efficiency of attaching the boards to each other can be greatly improved.
